CVI provides a thread pool and asynchronous timer mechanism for multithreading. Vein display thread pools are suitable for tasks that are executed multiple times or in cycles, while asynchronous timers are suitable for tasks that are performed at fixed intervals. In addition, the measurement and control system itself has a high requirement for the acquisition frequency and requires a high-precision timer. The control software of the upper computer software includes three sub threads. Among them, the priority of the main thread is high, and secondly, it is considered that the command of the master controller and the alarm signal received and transmitted to the host computer by the slave controller should be received in real time, and the priority of the communication module is second only to the master thread. The display and drawing thread has a low priority and is executed only when the CPU is idle, which not only meets the requirements of the system, but also ensures the real-time requirements of the measurement and control system.
our dished heads are used in a variety of applications and industries such as storage tanks, pressure vessels, road tank, food processing operations, chemical plants ,Nuclear operation, Oil Refining, Architectural feature, power generation.
Due to our forming experience and equipment, we can spin or press the first part of the process of forming your products, It depend on the thickness and material performance,
Our main products are 2:1 SE dished heads, Torispherical heads, Cones,Hemispherical Heads etc
Choosing the right type is the key decision for each customer and one for which our experience team to happy to give advice, simple speaking, the torispherical heads, the less ressure it can withstand, Conversely, the deeper dished heads, for example Elliptical heads, hemispherical, the greater pressure it can take.
Our in house-capability to form dished heads by cold press brings major benefits to our customers and sets us apart from others dished heads manufactures
For carbon steel dished heads, we can forming this dished heads from 76-9000mm in diameter and below 250mm in thickness
The general forming process as the below sketches

Multi-thread real-time acquisition processing Compared to the CVI Timer control, the asynchronous timer is based on multi-threaded processing and Windows multimedia timers perform timing operations with a high priority. However, different machines can be set up with different intervals than the Boshan fire pump. If you set a time interval smaller than the system's available large resolution, the behavior is unpredictable. At the same time, a multimedia timer thread runs all the asynchronous timer callback functions registered in a single program. To use multiple threads, a thread pool must be used.
1,Our material (hot Rolled Unalloyed structural steel, high and low temperature steel, High Alloy steel)
We have no carbon steel plates in our stock and most of plates are from Chinese steel market or mill. Meanwhile As Japanese owed company, We can also source the plates from Japanese ex-mill if end user can`t accept ex-chinese mill.
Basically the delivery time shall be below 20days for dished heads if plates are from steel market. and Max plates width from them is below 2200mm. it means that the seamless dished heads diameter shall be below about 1800mm.
The max width CS plates that Chinese mill can do is below 4700mm,and dished heads can be seamless below 3800mm in diameter.
Realization of Multithreading Method in Testing and Control System of Test Bed
In the test and control of the test bed , the load control system has high requirements for real-time performance. For such systems, multi-threaded programming is generally used. Therefore, data security between multiple threads needs to be considered.
